如何在android中的特定节点写入XMl？

Question

我有一个像这样的XML文件

<?xml version="1.0" encoding="utf-8"?>

        numLines="0"

    <Question

        name="Question #3" 
        type="Date" 
        allowBackButton="true" 
        isRequired="true" 
        numLines="0" 
        questionIndex="3">
        <QuestionText>What is Your Date of birth?</QuestionText>
        <Answers></Answers>
        <Response respondedTimeStamp=""></Response>
        <OnChoice></OnChoice>
    </Question>
</Questions>
</Survey>

现在在我的应用程序中，我使用SAX解析器来阅读这些内容。 现在每个问题都有一个问题类型，你可以在我的xml中看到。

<Question
    id="q1"
    name="Question #1" 
    type="SingleChoice" 
    allowBackButton="false" 
    isRequired="true" 
    numLines="0" 
    questionIndex="1">

基于此我在列表视图中填充了我的Checkbox。

现在我要做的是假设任何用户在标签中检查项目

<Response respondedTimeStamp=""></Response>

我必须将时间戳和响应值写为该特定问题的文本。

那我该怎么做？

您可以使用 XStream 库将数据写入xml。
